Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a preheating roller for corrugated paper production. Background Art

[0002] Corrugated paper is a plate-like material made of noodle paper and corrugated paper formed by corrugating rollers. As an environmentally friendly, lightweight and durable packaging material, corrugated paper has broad application prospects in modern logistics, packaging and other fields. When corrugating, the moisture content of the base paper entering the single-facer is best at 9%-12%. This moisture content is achieved by the temperature control of the preheating roller and preheating machine on the single-facer. Preheating can increase the temperature of the corrugated paper, making the paper softer and easier to deform. This is very important for the subsequent printing process because it helps to improve the printing quality, reduce paper deformation and warping, and at the same time enhance the adhesion between ink and paper, making the printed image clearer and more durable.

[0003] When the corrugated paper is preheated by the preheating roller, the corrugated paper is guided by the paper guide roller and then attached to the preheating roller for preheating. When the moisture content of the corrugated paper is low, the preheating area needs to be reduced, and when the moisture content of the corrugated paper is high, the preheating area needs to be increased. Since the adjustment range of the paper guide roller on the current preheating roller is small, the adjustment range of the contact area between the corrugated paper and the preheating roller is limited, and it is unable to effectively adapt to the preheating work of corrugated paper with different moisture contents, resulting in a poor preheating effect of the preheating roller. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 5 A preheating roller for corrugated paper production provided in this embodiment includes a bottom plate 1, a pair of bracket plates 2 are arranged on the upper side of the bottom plate 1, a roller body 4 is arranged on the top of the bracket plate 2 through a first bearing 3, a first paper guide roller 6 arranged parallel to the roller body 4 is arranged on the front side of the bracket plate 2 through a mounting seat 5, a connecting frame 10 rotating around the axis of the roller body 4 is arranged on the bracket plate 2, a second paper guide roller 12 arranged parallel to the roller body 4 is arranged on the connecting frame 10 through a connecting seat 11, and the second paper guide roller 12 rotates around the axis of the roller body 4 through the connecting frame 10 to adjust the bonding area between the corrugated base paper and the roller body 4.

[0026] In the utility model, the preheating roller is installed and fixed through the bottom plate 1, the corrugated paper passes through the bottom of the second paper guide roller 12, then passes through the top of the roller body 4 and passes through the bottom of the first paper guide roller 6, the corrugated paper between the first paper guide roller 6 and the second paper guide roller 12 is attached to the roller body 4 for preheating, when the water content of the corrugated paper is low and the preheating area needs to be reduced, the connecting frame 10 rotates to make the second paper guide roller 12 on the connecting seat 11 close to the first paper guide roller 6, when the water content of the corrugated paper is high and the preheating area needs to be increased, the second paper guide roller 12 rotates through the connecting frame 10 to make the second paper guide roller 12 rotate in the direction away from the first paper guide roller 6;

[0027] It should be noted that the roller body 4 is rotatably mounted between the bracket plates 2 via the first bearing 3. The roller body 4 has a cavity for containing heat transfer oil. During preheating, the heat transfer oil enters the cavity inside the roller body 4 through the pipe openings at both ends of the roller body 4, thereby performing preheating work.

[0028] Specifically, Figure 2-Figure 4 As shown, the bracket plate 2 is provided with a plurality of positioning screw holes 21 arranged circumferentially around the axis of the roller body 4, and the connecting frame 10 is penetrated by positioning bolts 101 matching the positioning screw holes 21, and a handle 102 is provided at one end of the positioning bolts 101 away from the bracket plate 2.

[0029] When adjusting the second paper guide roller 12 according to the moisture content of the corrugated paper, first loosen the positioning bolt 101 on the connecting frame 10 through the handle 102 to disengage the positioning bolt 101 from the positioning screw hole 21, and then rotate the connecting frame 10 to rotate the second paper guide roller 12 around the axis of the roller body 4, so as to adjust the relative position of the second paper guide roller 12 and the first paper guide roller 6, and then adjust the contact area between the corrugated paper and the roller body 4. After the adjustment, screw the positioning bolt 101 into the corresponding positioning screw hole 21.

[0030] It should be noted that the positioning screw holes 21 are arranged circumferentially around the axis of the roller body 4. A plurality of positioning screw holes 21 can ensure that the connecting frame 10 can find the positioning screw hole 21 corresponding to its position after rotation, thereby achieving the positioning and fixation of the connecting frame 10 after rotation.

[0031] Specifically, Figure 1 and Figure 4 As shown, an adjusting bolt 104 is provided on the top of the connecting frame 10, and the top of the connecting seat 11 is connected to the bottom of the adjusting bolt 104 through a connecting sleeve 112, a slide rail 111 is provided on the connecting seat 11, and a slide groove 103 matching the slide rail 111 is opened on the connecting frame 10.

[0032] Among them, the bottom of the adjusting bolt 104 is rotatably connected to the connecting seat 11 through the connecting sleeve 112. When the adjusting bolt 104 rotates at the top of the connecting frame 10, the adjusting bolt 104 will move up and down under the action of the thread, thereby driving the connecting seat 11 to move on the connecting frame 10, and then the distance between the second paper guide roller 12 and the roller body 4 on the connecting seat 11 can be adjusted, and the corresponding distance adjustment can be performed according to the paper thickness of the corrugated paper and the traction tension of the corrugated paper. When the connecting seat 11 moves, the slide rail 111 and the slide groove 103 can play a guiding role on the one hand to ensure the smooth movement of the connecting seat 11 on the connecting frame 10, and can play a limiting role on the other hand to prevent the connecting seat 11 from being offset and detached from the connecting frame 10 when moving.

[0033] Specifically, Figure 1 and Figure 5 As shown, both ends of the second paper guide roller 12 are provided with connecting ends 122 through the mounting groove 121, and one end of the connecting end 122 located inside the mounting groove 121 is provided with a slide 123 that matches the mounting groove 121, and a spring 124 is provided between the slide 123 and the inner wall of the mounting groove 121, a pair of limit strips 125 are provided on the slide 123, and a limit slot 126 that matches the limit strip 125 is opened on the inner wall of the mounting groove 121.

[0034] The connecting ends 122 at both ends of the second paper guide roller 12 can be squeezed and contracted in the installation groove 121. When the second paper guide roller 12 needs to be disassembled for inspection and repair or installed, the connecting end 122 is first squeezed to compress the spring 124 and then contracted in the installation groove 121, so that the second paper guide roller 12 can be conveniently installed and disassembled, and the second paper guide roller 12 can be easily inspected and cleaned. The limiting strip 125 on the slide 123 and the limiting groove 126 in the installation groove 121 can play a guiding role, and at the same time avoid the connection end 122 and the second paper guide roller 12 from rotating and causing wear.

[0035] It should be noted that the structure of the first paper guide roller 6 is the same as that of the second paper guide roller 12 , and both ends thereof also have retractable connecting ends 122 , thereby facilitating the inspection and cleaning of the first paper guide roller 6 .

[0036] Specifically, Figure 2 As shown, a second bearing 8 is provided at the bottom of the connecting frame 10 through a mounting sleeve 9, an outer sleeve 7 coaxially arranged with the roller body 4 is provided on the bracket plate 2, the second bearing 8 is sleeved on the outside of the outer sleeve 7, the diameter of the outer sleeve 7 is larger than the diameter of the first bearing 3, and the outer sleeve 7 is detachably mounted on the bracket plate 2 through a mounting ring.

[0037] Among them, the outer sleeve 7 is sleeved on the outside of the roller body 4 passing through the first bearing 3.
